An error guard that stops your AI agents before the costly mistake.
Everyone is talking about insurance for AI mistakes. The cheaper answer is not making them: a guard that checks every refund, payment and message against your rules and holds the ones that look wrong.

- Sits between your agents and the systems they act on

Week three — live beside your team
- Approval inbox, alerts and the audit export
Questions
01Does it slow my agents down?
Only the actions that trip a rule wait for a human. Everything else is checked in milliseconds and passes straight through.
02Which agents can it watch?
Any agent that acts through an API, a webhook or a queue, ours or someone else’s. We integrate at the action layer, not the model.
03Is this insurance?
No. Insurance pays after the mistake. Sentinel is the layer that stops the mistake, and the log you would hand to an insurer if you later buy cover.
